You would need some loops to do that. What code have you tried?
Post your code and show its output
or post the error messages you are getting.

can you solve the posted example ?
no error message i want idia doing this
thanks again

Just post code to solve the posted example. Leave the rest of your code off.
Make a simple program that compiles and executes with a 2D array and some loops for solving the shown example.

i want code solve posted example

You should hire a programmer if you want someone to write your code for you.
We'll help you get your code to work. We don't write code to solve peoples' problems.

If that is true then this little bit of code will be much simpler.
All it needs is some loops and if statements.

Then you have come to the wrong place.

I'm unclear about the example output you've posted back in the original post. In your problem statement, you stated the following.

i want to say if all elements of row >=3 put all elements of this row=0

---

Don't you want the first row to be changed to 0's instead of the second row?

I don't understand the condition why a row should be set to zeros, but the code is as simple as this:

Code:

---

for (int i= 0; i < matrix.length; i++)
  if (hyzoomCondition(matrix[i]))
      Arrays.fill(matrix[i], 0);

kind regards,
